Frequently Asked Questions

We recommend using LISTERINE^® mouthwash twice daily, as this reflects the most recent scientific evidence available to us.

Our research consistently suggests that using a fluoride mouthwash with plaque-reducing ingredients to rinse after brushing is an effective way to control plaque to maintain good gum health and help strengthen teeth.

Scientific research also shows that using fluoride containing mouthwash, rather than rinsing with non-fluoride mouthwash or water after brushing, can help protect and maintain the levels of fluoride you get from your toothpaste.

If you have any further concerns regarding your oral health, we advise that you follow the advice of your dentist or dental professional for your specific oral healthcare needs.
